Gamers line up for Vita at Yodobashi Camera in Shinjuku on launch day.

Media Create will release its full set of weekly sales stats early tomorrow (actually around midnight tonight), but the firm has given advanced stats to the press.

Vita sold 325,000 units in its first week (covering the 17th and 18th), according to Media Create stats (as reported at IT Media). This is similar to the 321,000 unit figure that Enterbrain reported earlier in the week.

Media Create estimates that the system's sell-through rate is 65%. This is based off an estimate of 500,000 units shipped, which matches a figure shared in a column that was posted to Nikkei earlier today (it's possible that the Nikkei column was based off Media Create's shipment estimates).

Media Create CEO Atsushi Hosokawa provided some commentary on the initial performance. "The shipment was abundant, so it seems that there were hardly any reports of inability to buy due to shortages. Regarding sold units, to be honest we would like to have seen it sell a bit more, but you can say that it reached a certain level of success."

Hosokawa blamed the relatively slow start on price, noting that when you include a game and required accessories, the system ends up costing 40,000 yen. He also noted that the system did not have a system seller at launch.

One other factor could be holding back the Vita: its predecessor, the PSP. Sony sold 60,000 units of the aging hardware this past week, Hosokawa said.
